I’m currently rotoscoping a piece of paper and I’ve restarted the process so many times at this point. I have outlined it, but randomly, the points just seem to lose track occasionally. I had to split these into several layers only doing two frames at a time and just turning them off just to circumvent this, but even this eventually fails - randomly.
I have a saved project file, but reopening it will most likely mess with the bezier points for some reason.
Image example. I have open a saved project file with the rotoscope I want, I then exported these shapes into a clean file. The re-export is not correct at some points and is representative of what could possibly happen when I just simply re-open the saved file with the presume final rotoscope:
There is seemingly no tracking on the layer. I have tried different layers. The final project literally looks as it should until re-opening.
Rexporting the final project as an EXR into Nuke also lends the same issue. Here are some comparison images:
(Ignoring the slipping on the left side of the piece of paper, I have roto’d the entire of body and that’s intentional - the slipping is an issue on the right side):
Specifically, I noticed it always started slipping towards the middle. The start and end frames never changed.
